“The inhabitants of the towns of Arabia and Egypt,” says Burckhardt, “are in the daily habit of taking in wedlock Abyssinian as well as Negro slaves;”[101] and, in a subsequent part of his travels, the same intelligent author describes a class of people in Nubia who are the direct offspring of this mixture of race, and who seem, from his description, to answer the characters of the Copts themselves. “The Nouba slaves (among whom must be reckoned those who are born in Senaar of male Negroes and female Abyssinians) form a middle class between the blacks and the Abyssinians. Their features, though they retain evident signs of Negro origin, have still something of what is called regular; their noses, though smaller than those of Europeans, are less flat than those of Negroes their lips are less thick, and the cheek bones less prominent. The hair of some is woolly but among the greater part it is similar to the hair of Europeans, but _stronger_, and always curled.” Another, and yet more striking example of the Negroid conformation is seen in the vast Foulah or Fellatah population of central Africa, which is now spread over a region of fifteen hundred miles from east to west, and five hundred miles from north to south. That they are a mixed progeny of Arabs, Berbers and Negroes, no longer admits of a reasonable doubt. Such is the opinion of D’Avezac and Hodgson, Vater, Adelung, and most other inquirers. “In the midst of the Negro races,” observes M. D’Avezac, “there stands out a métive population, of tawny or copper colour, prominent nose, small mouth, and oval face, which ranks itself among the white races, and asserts itself to be descended from Arab fathers and Taurodo mothers. Their crisped hair, even woolly, though long, justifies their classification among the _Oulotric_ (woolly-haired) populations; but neither the traits of their features, nor the colour of their skin, allow them to be confounded with Negroes, however great the fusion of the two types may be.”[102] These and other facts derived from the slave trade, when considered in connexion with the Negro colonization of Nubia in the reign of Dioclesian, will account, I may repeat, not only for every blending of race observable in that country, but also assists us in tracing the origin of the Copts;—not to a _period_ of time, it is true, but to circumstances which have been in operation for ages, and which were once, in all probability, far more active than they are at present. By the kindness of Mr. Gliddon I possess three Coptic skulls, two of which are adult, and are accurately sketched in the subjoined drawings, (A and B.) [Illustration]
